Is Fluent capable to report values at a certain point or reference plane of my geometry?

Until now, I am defining a reverence plane when I set up the geometry in gambit. Then, when I want Fluent to return the values of the simulation result at that plane, I am using write -> profiles and select the plane and the type of results.

That is the way, I DON'T want to do it in future. Is there any other? Because when I set up the geometry, I don't know, where I do my measurements to compare the values with simulation results.

In fluent you can add points, lines, rakes, surfaces or iso-surfaces. All of those are available under the Surface menu. You can then use any of those to get the values out of the simulation (either write->profiles, or to view them right in fluent use report->surface integrals).
